Two friends Chef and Chefina are currently on floors A and B respectively. They hear an announcement that prizes are being distributed on the ground floor and so decide to reach the ground floor as soon as possible.
Chef can climb down X floors per minute while Chefina can climb down Y floors per minute. Determine who will reach the ground floor first. In case both reach the ground floor together, print Both.
• The first line of input will contain a single integer T. denoting the number of test cases.
The first line of each test case contains four space-separated integers A, B, X, and Y - the current floor of Chef, the current floor of Chefina, speed of Chef and speed of Chefina in floors per minute respectively.
For each test case, output on a new line:
• Chef if Chef reaches the ground floor first.
• Chefina if she reaches the ground floor first.
⚫Both if both reach the ground floor at the same time.
You may print each character of the string in uppercase or lowercase. For example, the strings
CHEF, chef, Chef, and chEF are all considered the same.
To determine which of Chef and Chefina will reach the ground floor first, you can compare the time it will take each of them to reach the ground floor.
You can do this by dividing the distance they each need to travel (the difference between their current floor and the ground floor) by their speed in floors per minute. The one with the shorter time is the one who will reach the ground floor first. If the times are equal, then both will reach the ground floor at the same time.
Here is some example code in Python that demonstrates how you might solve this problem:
`# Read the number of test cases t = int(input()) # Loop over the test cases for _ in range(t): # Read the current floors and speeds a, b, x, y = map(int, input().split()) # Calculate the time it will take each of them to reach the ground floor chef_time = (a - 0) / x chefina_time = (b - 0) / y # Determine which one reaches the ground floor first if chef_time < chefina_time: print("Chef") elif chef_time > chefina_time: print("Chefina") else: print("Both")`
This code reads the input for the problem, calculates the time it will take each of Chef and Chefina to reach the ground floor, and then prints the appropriate output based on who reaches the ground floor first.
I hope this helps! Let me know if you have any questions.
